Problem 1: A plant wholesaler, who uses only botanical and no common names, except for named cultivars and trademarks has a listing Euonymus nana 'Turkestanica' The plant List (https://theplantlist.org) doesn't have a species nana. It does have nanus. There is a variety turkestanicus. Now my newbie understanding of nomenclature is that their listing indicates that Turkestanica is a named cultivar of the species E. nana. But the lack of a 'nana' on the plant list, and the closeness of the variety and the named cultivar make me think someone is being sloppy, possibly their supplier. *** Problem 2 Another one I'm seeing as a sizeable fraction (10-20%) is Eleagnus instead of Elaeagnus. I can find no support that the first is a valid synonym. This is a recurring problem: I want my website to be accurate, but I also have to deal with current availability lists that have errors, so I'm trying to figure out how to best deal with these.
